other nested groups) connected through a unique logic operator (AND is assumed for 'space')

 | GroupElement(Configuration) |
Creates an empty group.
|
| GroupElement(String, Configuration) |
Creates a group containing the expression |
 | AddMissingOperators()()()() |

|
| AddMissingOperatorsAsAnd()()()() | Obsolete.
Obsolete - Renamed to AddMissingOperators, please use new name.
|
 | ChildElements |
Returns a list of Element objects, representing the sub elements of the query.
|
| Configuration |
The instance of the Configuration class that holds the settings to be used.
(Inherited from Element.) |
| Content |
Returns a string representing the content of the element, this should typically be;
WordElement.Content => theWord
NotWordElement.Content => -theWord
GroupElement.Content => null
PhraseElement.Content => thePhrase (no quotes)
(Overrides Element.Content.) |
| CreateLexiconQueries(SearcherIO) |
Creates the LexiconQuery for this element.
(Overrides Element.CreateLexiconQueries(SearcherIO).) |
| CreateWordSubgroup(String) |
Creates an Element based on the parameter.
|
 | elementQueryCollection |
The lexicon queries used for the element
(Inherited from Element.) |
| elements |
The Element objects within the group.
|
| Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
| Finalize()()()() | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetChildElementContents()()()() |
Returns ArrayList of all child element .Content properties
|
| GetHashCode()()()() | Serves as a hash function for a particular type. (Inherited from Object.) |
 | GetIgnoredWords()()()() |
Returns the stop words from the original query that were ignored.
(Overrides Element.GetIgnoredWords()()()().) |
| GetMatchingDocumentIDs(SearcherIO, IntHashtable, SearchOptions, Hashtable) |
Gets all document IDs matching this group.
(Overrides Element.GetMatchingDocumentIDs(SearcherIO, IntHashtable, SearchOptions, Hashtable).) |
| GetType()()()() | Gets the type of the current instance. (Inherited from Object.) |
| GroupOperator | The logic operator that all elements in the group are bound with (AND or OR).
|
| IsStopWord()()()() |
Whether is stop word.
(Inherited from Element.) |
| MemberwiseClone()()()() | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ParseExpression(String) |
Loads the elements field with elements (words, phrases, groups, logic operators) in expression.
|
| RemoveOperatorAmbiguities()()()() |
Removes operators ambiguities
(if there are both "AND" and "OR" operators in a group, re-adjust groups like: (x OR y) AND z)
|
| RunLexiconQueries(SearcherIO) |
Runs lexicon queries for every element in the group, allowing occurrence lookups to occur.
|
| ToString()()()() | Returns a string that represents the current object. (Inherited from Object.) |
